I like the ability to invite multiple people at one time, the ability of the inviter to change the wording of the invitation and the ability to invite to specific groups at the same time. If 1.5 allows for those things, as shipped, we probably don’t need IA. If it would allow me to designate inviters one-by-one, I would be thrilled.

This plugin is also very important if you are using BP Followers, and have Friends de-activated. This is the only way you can add people to your groups (default bp functionality only allows you to invite “friends” to groups).
